CAR-VENTILATOR.

SPECIFICATION forming part of Letters Patent No. 603,1 15, dated April 26, 1898. Application filed November 18 1896. Serial No. 612,544. (No model.)

To all whom it may concern:

Be it known that we, JACOB NORLING and CHARLES E. JOHNSON, citizens of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented a certain new and useful Improvement in Car- Ventilators, which is fully set forth in the following specification, reference being had to the accompanying drawings, in which- Figure l is a plan view of a portion of a carroof, showing the lid thrown back and the ventilator raised. Fig. 2 is a vertical longitudinal section on the line 2 2 of Fig. 1, showing in dotted lines the lid in position upon the ventilator. Fig. 3 is a vertical cross-section on the line 3 3 of Fig. 2 in the direction of the arrow. Fig. 4: is a vertical cross-section on the line i 4: of Fig. 2 in the direction of the arrow. Fig. 5 is a vertical longitudinal section similar to that of Fig. 2, showing the ventilator housed and the lid still thrown back. Fig. 6 is a horizontal section on the line 6 6 of Fig. 5.

Our invention is intended to be used in connection with cars, especially of the combined ventilator and refrigerator type, and, more particularly, is adapted to be applied to the ice-apertures formed in the roofs of such cars, in the opposite ends thereof, through which the cars are iced.

Referring to the drawings by letter, A represents a portion of the roof of such a car, which roof is preferably formed double, OOIIlprising the upper layer A and the lower layer A inclosing between. them the air-space A B designates one of the ice-apertures through such a roof. At its end nearest to the end of the car it is provided with a strip 13, forming an upright wall, and on each side with a similar strip 13 along the lower inside surface of which is formed ahorizontal channel or guideway 12. Within the space A between the layers of the roof and in continuation of the strips B are disposed two strips or partitions B connected at their ends farthest from the ice-apertures by the cross-strip B whereby there is formed between the two layers of the roof of the car an inclosed recess or hood B which is adapted to receive the ventilator when housed. The guideways or channels I) are continued on the inner surfaces of the strips B The bottom of the hood adjacent to the ice-aperture extends out from beneath the top thereof to form a narrow sill b.

A lid 0, adapted to close the ice-aperture, is hinged, preferably, to a strip 0, secured at that edge of the aperture farthest from the end of the car. A similar cross-strip O supports the free edge of the lid when the same is thrown back onto thecar-roof. The under surface of the lid O is provided with two strips (3 near its side edges, terminating short of the free edge of the lid, and with a cross-strip 0 secured along the said free edge of the lid. The lid is perforated, as at 0.

Over the mouth of the hood B there is hinged a long narrow guard or shield D, preferably of sheet metal and provided with a handle cl. Then the said guard is in normal position, it is swung downward to close the mouth of the hood. It may, however, be swung up into the position shown in dotted lines in Fig. 5.

The screen-frame E of the ventilator comprises the npper cross-piece E, the lower cross-piece E and the two side pieces E which are preferably rigidly held together by the diagonal brace e and the two angular braces e, disposed as particularly shown in Figs. 3 and 4. On the outside of the screenframe when the same is raisedthe under surface of the said frame when it is lowered-is stretched a screen B. At each bottom corner of the screen-frame is secured 2. lug 6 which is adapted to travel in one of the channels or guideways b in the side of the ice-aperture. Finally, to the upper edge of the screen-frame is secureda hasp E in con 3' unction with which there is preferably used a padlock E.

To each side of the screen-frame is hinged an approximately triangular side wing F, which may be made of sheet metal and strengthened by the brace f.

The operation of the devices, the construction of which has been shown and heroinabove described, is as follows: When the ventilator is raised, it is in the position shown particularly in Figs. 2 and 8, the screen-frame upright and abutting against the end wall B of the ice-aperture, the side wings F swung out at right angles to the said screen-frame, the edges of the free ends resting upon the sill b, the shield or guard D swung down in its normal position, holding apart the said free ends of the side wings, and the lid 0 swung down over the top of the ventilator in the position shown in dotted lines in Fig. 2. The strips 0 form supports for the upper edges of the side wings against which they abut, the strip 0 holds the lid firmly in relation to the screen-frame itself, while the hasp E projecting through the aperture 0, is adapted to be locked by thepadlock E or otherwise, and the whole ventilator is firmly secured. The ventilator is safe against displacement and the car against intrusion.

When the ventilator is to be housed, the lid 0 is swung back onto the car-roof, the shield D is swung up, and the side wings F are folded in against the screen-frame one over the other. The said screen-frame, with its folded lids, is then slid toward the hood, the lugs 6 moving in the guideways b. At the same time the screen-frame is lowered intoa horizontal position with the folded side wings uppermost, and in such position is furtherslid into the hood 13 where it occupies the position particularly shown in Fig. 5, and the shield D is swung down to cover the mouth of the said hood. The lid 0 may then be swung over to close the mouth of the ice-aperture and be so secured.

It is obvious from the construction of this ventilator that when the same is up in operative position it may be attached to the lid in a simple but effective manner and secure the car against intrusion. It will further be seen that when the lid is housed it is completely out of the way and free from danger of injury when icing up the car. This form of ventilator is, moreover, not only simple in its operation, but also in its construction, comprising but few parts, and when out of use housed without waste of space.

Ventilators of this general type have been previously used, in some of which the side wings and screen are hinged directly to the lid and are subject to becoming broken or mutilated. In others the side wings have been hinged to a screen-frame and adapted to fold upon the said frame when the ventilator is slid into a hood formed in the lid itself, with which construction the weight and bulk of the lid is greatly increased and the parts of the Ventilator are still liable to injury in the opening and shutting of the lid, while in other ventilators, finally, a single screen-frame and screen without any side wings and adapted to remain horizontal has been constructed to slide out from a hood in or on the car-roof across the ice-aperture, resultingin but a limited amount of ventilation. It will readily be seen that none of these constructions involve the features or secure the advantages of the construction made the subject of this application.

Having thus described our invention, what we claim, and desire to secure by Letters Patent, is+
